So I've been trying to Dagon Age, because its amazing, but my computer chugs like the little engine that could. My specs are decent and this really shouldn't happen. I also recently updated the drivers, so thats not the problem.

AMD Phenom 9600 2.2 gig quad
Geforce 9800gtx+ 512mb
4 gigs of ram

Interesting enough, my framerate at 1600x1050 with all the bells and whistles is noticably better than it at at lower res with everything turned down all the way.

Also, sometimes it runs flawlessly, but for whatever reason, as I play on, it gets continually worse. Please help.
